solrj操控sorl，增删改查

maven

<dependency>            <groupId>org.apache.solr</groupId>            <artifactId>solr-solrj</artifactId>            <version>4.10.4</version>        </dependency>        <!-- https://mvnrepository.com/artifact/commons-logging/commons-logging -->        <dependency>            <groupId>commons-logging</groupId>            <artifactId>commons-logging</artifactId>            <version>1.1.1</version>        </dependency>

增加的大体思路

1. 第一，准备好一个sorl项目并启动，得到一个sorl的url。
2. 第二，导入的jar包中得到sorl的客户端对象HttpSolrServer
3. 第三，new一个doc对象，添加到HttpSolrServer
4. 第四，提交

删除大体思路

得到连接，根据条件删除，后面是时间（条件也可以是*：* 表示全部）

 @Test    public void testSearch2() throws Exception {        String baseURL="http://localhost:8081/solr/collection1";            HttpSolrServer httpSolrServer = new HttpSolrServer(baseURL);        httpSolrServer.deleteByQuery("name:刘中华", 100); }

查询大体思路

 @Test    public void testSearch3() throws Exception {        String baseURL="http://localhost:8081/solr/collection1";            HttpSolrServer httpSolrServer = new HttpSolrServer(baseURL);        //new 一个查询对象        SolrQuery solrQuery = new SolrQuery();        //向查询对象里面增加条件   (增加基本的查询条件，想当于   solrQuery.set("q","name:刘中华");)        solrQuery.setQuery("name:刘中华");        //增加过滤条件//      solrQuery.set("fq","desc:程序员");        //价格排序//      solrQuery.addSort("price",ORDER.desc);        //分页        solrQuery.setStart(0);        solrQuery.setRows(5);        //高亮，默认域        solrQuery.set("df", "name");        //指定只查询某个域        solrQuery.set("fl", "id,name");        //高亮显示，开启高亮        solrQuery.setHighlight(true);        //指定高亮域        solrQuery.addHighlightField("name");        //指定前缀，后缀        solrQuery.setHighlightSimplePre("<span style='color:red'>");        solrQuery.setHighlightSimplePost("</span>");        //执行查询，得到结果集，同时也得到高亮部分的结果集        QueryResponse query = httpSolrServer.query(solrQuery);        SolrDocumentList doc = query.getResults();        Map<String, Map<String, List<String>>> highlighting = query.getHighlighting();        //遍历        System.out.println(doc.getNumFound());        for(SolrDocument d : doc){            System.out.println(d.get("name"));            System.out.println(d.get("id"));            System.out.println("-----------------");            Map<String, List<String>> map = highlighting.get(d.get("id"));            List<String> list = map.get("name");            System.out.println(list.get(0));        }    }
